(Cleaner for descaling)
The descaling cleaner according to the present embodiment includes a cloth base material, a plurality of three-dimensional elements including abrasive grains and a binder, and an adhesive layer for joining the cloth base material and the three-dimensional element. The plurality of three-dimensional elements and the adhesive layer are arranged on one surface side of the cloth base material, and the plurality of three-dimensional elements form the polished surface of the descaling cleaner.

In the water stain removing cleaner according to the present embodiment, since a plurality of three-dimensional elements including abrasive grains and a binder form a polished surface, the water stains are effectively held by the abrasive grains held in the three-dimensional elements by the binder. Can be removed.

Further, in the present embodiment, since the abrasive grains that have fallen off from the three-dimensional element enter the gaps between the three-dimensional elements, the formation of scratch marks due to the dropped abrasive grains can be avoided, and good scratch prevention performance can be obtained.

Further, in the present embodiment, the abrasive grains may be dispersed in the three-dimensional element, and at this time, the three-dimensional element is gradually scraped during use, so that new abrasive grains always appear on the polished surface. Therefore, the descaling performance is maintained for a long time, and it is possible to avoid scratches on the treated surface due to changes in the force applied during work.

Further, in the present embodiment, since the polished surface is formed of a plurality of three-dimensional elements and the base material is a cloth base material, the polished surface and the base material have excellent flexibility and followability to curved surfaces and irregularities. Excellent for.

Examples of the cloth base material include knitted cloth, woven cloth, and non-woven fabric. Specifically, for example, as the knitting fabric, a weft knitting fabric knitted by a flat knitting machine, a circular knitting machine, etc., a warp knitting fabric knitted by a warp knitting machine such as a tricot knitting machine, a Raschel knitting machine, etc. And so on. Examples of the woven fabric include plain weave cloth, satin weave cloth, and diagonal woven cloth. Examples of the non-woven fabric include air-laid non-woven fabric, spunlace non-woven fabric, chemical bond non-woven fabric, thermal bond non-woven fabric, spun-bond non-woven fabric, needle punch non-woven fabric, melt blown non-woven fabric and the like.

The material of the cloth base material is not particularly limited, and for example, polyester, nylon, polyacrylonitrile, vinylon, vinylidene, polyvinyl chloride, polyurethane, polyethylene, polypropylene, polybutene, polyclar, acetate, triacetate, cubra, polynosic, rayon, and promix. It may be a synthetic resin such as cotton, linen, hair, silk, pulp or the like, or it may be a natural material.

The basis weight of the cloth base material may be, for example, 6 g / m ² or more, and preferably 10 g / m ² or more. This makes it easy to obtain suitable flexibility and strength for cleaner applications. The basis weight of the cloth base material may be, for example, 1000 g / m ² or less, and preferably 700 g / m ² or less. This makes it easier to follow curved surfaces and irregularities, and makes it easier to polish narrow spaces such as faucets.

The cloth base material preferably has a stiffness value of 40 g / 12.7 mm or less, and more preferably 25 g / 12.7 mm or less. This imparts appropriate flexibility to the descaling cleaner, and improves the ability to follow curved surfaces and irregularities. Further, the stiffness value of the cloth base material may be 0.01 g / 12.7 mm or more, or 0.05 g / 12.7 mm or more from the viewpoint of easily ensuring mechanical strength and durability. ..

In the present specification, the stiffness value is determined by using a loop stef nestester (Toyo Seiki Seisakusho Co., Ltd.) to push the top of a loop-shaped sample having a width of 12.7 mm and a length of 60 mm with an indenter to the top side of the loop. The value of the load when the base side is in contact with the base side is shown. Specifically, it is measured by the following procedure.
(1) Cut the measurement sample into strips with a width of 12.7 mm and a length of 150 mm.
(2) The cut sample is fixed between two magnet chucks (thickness 15 mm) facing each other at a distance of 90 mm.
(3) The distance between the magnet chucks is set to 0, and the sample is formed in a loop shape having a length of 60 mm.
(4) A disk-shaped indenter is pressed against the top of the loop to compress the loop, and the load required for pressing is measured. The pushing speed is 3.3 mm / sec, and the relationship between the pushing distance and the load is graphed.
(5) When the top side and the base side of the loop start contacting, an inflection point is observed in the graph. The same measurement is performed three times, and the average value of the load at this inflection point is taken as the stiffness value.

An adhesive layer is provided on one side of the cloth base material. A part of one side of the cloth base material may be embedded in the adhesive layer. In other words, the adhesive layer may be impregnated on one side of the cloth substrate.

For example, fixing means to the holder may be provided on the other side of the cloth base material. As a result, the descaling cleaner can be used alone when polishing curved and uneven members, and the descaling cleaner can be supported by the holder when polishing a flat surface such as a mirror surface.

The fixing means to the holder may be, for example, a hook-and-loop fastener. More specifically, for example, the cloth substrate may have a loop-shaped locking portion on the other side. As a result, it can be easily attached to and detached from the holder having the hook-shaped locking portion. Further, the cloth base material may have a hook-shaped locking portion on the other side. As a result, it can be easily attached to and detached from the holder having the loop-shaped locking portion.

The adhesive layer is a layer that is arranged on one side of the cloth base material and joins the cloth base material and a plurality of three-dimensional elements. The adhesive layer may be, for example, a layer composed of an adhesive, or may be a layer composed of a cured product of the adhesive.

When the adhesive layer is a layer composed of an adhesive, the adhesive may be, for example, an acrylic adhesive, a rubber adhesive, a silicone adhesive, a urethane adhesive, or a polyester adhesive. Of these, acrylic adhesives are preferable.

When the adhesive layer is a layer composed of a cured product of the adhesive, the adhesive may be, for example, an acrylic adhesive, a rubber adhesive, a urethane adhesive, a polyester adhesive, an epoxy adhesive, or a silicone. It may be a system adhesive or the like.

In a preferred embodiment, the adhesive layer preferably contains an acrylic resin, and is preferably a layer composed of an acrylic pressure-sensitive adhesive or a cured product of the acrylic-based adhesive.

The adhesive layer may have an elastic modulus at 25 ° C. of 1 × 10 ⁴ to 1 × 10 ⁹ (Pa). According to such an adhesive layer, it is possible to obtain a descaling cleaner which is excellent in followability to curved surfaces and irregularities and also has excellent shape retention when attached to a holder and polished on a flat surface. When the adhesive layer is a layer composed of a pressure-sensitive adhesive, the elastic modulus of the adhesive layer at 25 ° C. is 1.0 Hz in frequency by a viscoelasticity measuring device (Advanced Rheometic Exhibition System (ARES) of Rheometric Scientific). When the adhesive layer is a layer composed of a cured product of the adhesive, it is measured by a viscoelasticity measuring device (RSA3 of Rheometric Scientific) under the condition of a frequency of 1.0 Hz.

The thickness of the adhesive layer may be appropriately adjusted within a range in which the followability to curved surfaces and irregularities can be sufficiently obtained. For example, the thickness of the adhesive layer may be 1 mm or less, preferably 0.5 mm or less. As a result, the flexibility of the descaling cleaner is further improved, and the followability to curved surfaces and irregularities is further improved. The thickness of the adhesive layer may be 10 μm or more, preferably 20 μm or more.

The three-dimensional element includes a plurality of abrasive grains and a binder for binding the abrasive grains. The three-dimensional element is three-dimensionally molded so as to be convex on one side of the cloth base material on the side opposite to the cloth base material. The three-dimensional element is adhered to the cloth base material by an adhesive layer provided on one side of the cloth base material. In other words, the three-dimensional element is provided on the surface of the adhesive layer opposite to the cloth substrate.

The abrasive grains may be any as long as they have a strength capable of removing water stains. Abrasive grains include, for example, diamond, aluminum oxide, silicon oxide, cerium oxide, zirconium oxide, chromium oxide, iron oxide, silicon carbide, tungsten carbide, zirconium silicate, garnet, flint, emery, topaz, zirconia, silicon nitride, and nitride. It may be abrasive grains such as boron, diatomaceous earth, and pebble. Of these, the abrasive grains are preferably diamond abrasive grains or aluminum oxide abrasive grains. When the abrasive grains are diamond abrasive grains, for example, better water stain removal performance can be obtained while sufficiently suppressing scratches on the glass surface. Further, when the abrasive grains are aluminum oxide abrasive grains, sufficient water stain removal performance can be obtained while remarkably suppressing scratches not only on the glass surface but also on the chrome-plated surface.

The average particle size of the abrasive grains is, for example, preferably 0.2 to 5 μm, and more preferably 0.5 to 3 μm. By making the average particle size smaller than the above upper limit value, scratches on the polished surface are further suppressed, and by making the average particle size larger than the above lower limit value, the scale removing performance tends to be further improved. The average particle size of the abrasive grains is measured by a laser diffraction / scattering type particle size distribution measuring device (LA-920, HORIBA, Ltd.).

A binder is a component that binds a plurality of abrasive grains to form a three-dimensional element, and can also be called a matrix that disperses a plurality of abrasive grains. The binder may contain, for example, a resin such as an acrylic resin, a phenol resin, an epoxy resin, a urethane resin, or a polyester resin. Of these, the binder preferably contains an acrylic resin. The binder may be, for example, a cured product of a curable composition containing an acrylic monomer and a polymerization initiator.

The strength of the binder is preferably 3 MPa or more, more preferably 5 MPa or more. As a result, the binding force of the abrasive grains is improved, and the descaling performance tends to be further improved. The strength of the binder is preferably 300 MPa or less, more preferably 200 MPa or less. As a result, when an excessive load is applied, the abrasive grains are likely to fall off, and scratches on the treated surface are more remarkably prevented. The strength of the binder indicates a value measured in a tensile test.

The three-dimensional element may have abrasive grains dispersed throughout it. Further, the three-dimensional element may have a multi-layer structure including a first layer as a base and a second layer containing abrasive grains provided on the first layer. At this time, the first layer does not necessarily have to contain abrasive grains. Both the first layer and the second layer may contain a binder.

In one aspect, the three-dimensional element may have a frustum structure in contact with the adhesive layer at the bottom surface. At this time, the upper surface of the frustum structure forms a polished surface. In such a three-dimensional element, scale is removed by the abrasive grains exposed on the upper surface of the frustum structure. The three-dimensional element is gradually scraped at the time of use, and new abrasive grains appear on the upper surface of the cone structure each time. Therefore, the descaling cleaner according to the present embodiment can maintain uniform descaling performance for a long time. The frustum structure may be a triangular frustum, a quadrangular pyramid, a polygonal frustum, or a truncated cone.

In one embodiment, the three-dimensional element may have a conical structure in contact with the adhesive layer at the bottom surface. At this time, the vertices of the cone structure form the polished surface. When such a three-dimensional element is used, the vertices are gradually removed, and the three-dimensional element forms a frustum structure. Abrasive particles dispersed in a three-dimensional element are exposed on the upper surface of the frustum structure, and water stains are removed by the abrasive grains. The pyramid structure may be a triangular pyramid, a quadrangular pyramid, a polygonal pyramid, or a cone.

In one embodiment, the three-dimensional element may have a columnar structure in contact with the adhesive layer on one bottom surface. At this time, the other bottom surface of the columnar structure (hereinafter referred to as the upper surface of the columnar structure) forms the polished surface. In such a three-dimensional element, scale is removed by the abrasive grains exposed on the upper surface of the columnar structure. The three-dimensional element is gradually scraped during use, and new abrasive grains appear on the upper surface of the columnar structure each time. The columnar structure may be a triangular prism, a quadrangular prism, a polygonal prism, or a cylinder.

In one embodiment, the three-dimensional element may have a structure in which a column (for example, a triangular prism) is laid on its side, that is, a column structure in which the column is in contact with the adhesive layer on one side surface. At this time, the side surface or the side surface facing the side surface in contact with the adhesive layer forms the polished surface. The pillar structure may extend in both directions toward its bottom surface, for example, to the end of the adhesive layer. The shape of the end portion of the pillar structure on the bottom surface side is not particularly limited, and for example, a surface perpendicular to the side surface may be formed, or the pillar structure may be formed in a hipped shape.

The height of the three-dimensional element (the height from the surface in contact with the adhesive layer to the top forming the polished surface) is not particularly limited, but may be, for example, 10 to 1000 μm, preferably 15 to 500 μm.

In the present embodiment, a plurality of three-dimensional elements are formed on the adhesive layer. In the present embodiment, since the fallen abrasive grains, fine dust, and the like can enter the gaps between the three-dimensional elements, the formation of scratch marks due to these can be avoided, and good scratch prevention can be obtained. Further, the cleaner for removing water stains according to the present embodiment has excellent flexibility and excellent followability to curved surfaces and irregularities because the three-dimensional elements forming the polished surface are divided into a plurality of parts.

The stiffness value of the descaling cleaner is preferably 45 g / 12.7 mm or less, and more preferably 30 g / 12.7 mm or less. As a result, the followability to curved surfaces and unevenness becomes better. The stiffness value of the descaling cleaner is preferably 0.05 g / 12.7 mm or more, and more preferably 0.1 g / 12.7 mm or more. As a result, there are effects such as obtaining moderate flexibility suitable for descaling work and facilitating attachment / detachment to / from the holder. In the present specification, the stiffness value of the descaling cleaner is measured by the same method as the stiffness value of the cloth base material.

In the present embodiment, since the polished surface is formed by a plurality of three-dimensional elements, it is easy to achieve the above-mentioned suitable stiffness value while maintaining excellent descaling performance. The stiffness value of the descaling cleaner can be appropriately adjusted by, for example, changing the rigidity and flexibility of the cloth base material and the adhesive layer. The composition and the like of the cloth base material and the adhesive layer may be selected so that the stiffness value of the descaling cleaner is within the above-mentioned preferable range.

(Kit for removing scale)
The descaling kit according to the present embodiment includes the above-mentioned descaling cleaner and a holder having a support means for supporting the descaling cleaner. According to such a descaling kit, for example, when polishing a flat surface such as a mirror surface, it is possible to efficiently perform the work by supporting the descaling cleaner with a holder.

The holder may have a grip portion that the operator grips by hand. The shape of the grip portion may be appropriately designed according to the intended use and the like.

The supporting means in the holder may be any means that can withstand the load due to the descaling work.

That is, the descaling cleaner may have a first locking portion for the hook-and-loop fastener on the surface opposite to the adhesive layer of the cloth substrate, and the holder may have the first descaling cleaner. It may have a second locking portion that engages the locking portion.

In a preferred embodiment, the descaling cleaner may have a loop-shaped locking portion on the surface opposite to the adhesive layer of the cloth substrate. Further, the holder may have a hook-shaped locking portion that engages with the loop-shaped locking portion of the descaling cleaner.
